Step 1: Prepare the Garlic Mashed Potatoes

1. In a large pot, place the potatoes and garlic. Cover with water, add a pinch of salt, and bring to a boil over medium-high heat.
2. Once boiling, reduce the heat to a simmer and cook for 15–20 minutes, or until potatoes are fork-tender.
3. Drain the potatoes and garlic thoroughly, then return them to the pot.
4. Add the softened butter, sour cream, and about half of the milk (or cream) to the potatoes. Mash until smooth, gradually adding more milk until desired consistency is reached.
5. Season generously with salt and pepper to taste. Cover and keep warm while you prepare the Alfredo sauce.

Step 2: Make the Alfredo Sauce Drizzle

1. In a small saucepan, melt the butter over medium heat. Add the minced garlic and cook until fragrant, about 1 minute.
2. Pour in the heavy cream, stirring to combine with the butter and garlic.
3. Gradually whisk in the Parmesan cheese, allowing it to melt fully into the cream.
4. Reduce the heat to low, stirring until the sauce is smooth and slightly thickened. Season with salt and pepper to taste.

Step 3: Serve and Garnish

1. Spoon the mashed potatoes onto a serving platter or individual plates.
2. Drizzle a generous amount of Alfredo sauce over the potatoes.
3. Sprinkle freshly grated Parmesan cheese and chopped chives on top for garnish.
